Application filed October 10, 1908. Serial N 0. 457,054..

To all whom it may concern:

Be it known that LRoBnnr S. ALLYN, a citizen of the United States, residing at New York, in the county of Kings and State of New York, have invented certain useful Improvements in Metal Corner? Beads, of which the following is a specification.

This invention relates particularly to what isknown as a plasterers corner. bead or straight edge.

The main object is to combine the advantages of strength, lightness and cheapness, and rapidity, ease and accuracy of erection.

It is formed from a strip of sheet metal and comprises a body portion extending longitudinally, a plurality of projecting lug and a plurality of arms out from the strip and folded laterally so as to afford convenient means for securing the body'to a corner post or other supporting member. Preferably the body is folded double, the arms along the edges are opposite each other and the planes of their greatest dimensions viz. length and width are parallel with the longitudinal axisv of the body. Alight and inexpensive form has a single thickness body with lugsand arms along one edge only.

The accompanying single sheet of drawings illustrates a number of adaptations of the invention.

Fig. l, is a side view of a single body type with paired arms. Fig. 5, is an end view of the same. Fig. 6, is an end view of amodification of the type of Fig. a.

In the form shown in Figs. 1 and2 the I body 1, is double, being formed from a strip of metal folded together along the longi- Fig. 8, is an end view of the same.

' tudinal center line or axis. The edges of A the strip are so cut as to provide a series of lugs such as 2, 2 and 3, 3 and arms such as 4, d and 5, 5 folded over as at 6, 6 and 7, 7, at the proper angle so as to afford convenient means of attachment to a corner post or beam. The arms may be perforated as at 8, 8, fornails, etc. Preferably the arms are arranged in pairs each arm 4 being opposite an arm 5/ This prevents the body from being misplaced in erection. The edges of the lugs 2 and 3 form abutments for positioning the body. I The lugs may be perforated if desired as at 9 to allow the plaster to pass through. The folding of the body and of the arms gives great rigidity, even in light gage material. Instead of folding the sides of the body togethertight as shown in Fig. 2, they may be left open as in F ig. 3, giving greater width to the outer edge. In this latter figure the arms 1 and 5 are folded inside the lugs 2 and 3 and the latter are bent outward. The angle between the arms is usually ninety degrees but it may be varied to accord with the require ments of use.

The body 11, in Figs. a and 5 is of single thickness and one edge is cut so as to leave lugs such as 12 and 13 and arms such as 14 and 15 folded as at 16 and 17. This brings two arms nearly opposite each other. The

lower part of Fig. 4, shows the position of the arms after cutting and before folding. If desired, tangs such as 18 and 19 may be struck from the metal of the body to afford openings and anchorage for the plaster or cement In Fig. 6 the arms let and 15 are bent out flat. This may be an advantageous form for some cases. The edge may be rolled over or otherwise formed as shown at 1 1 inthis figure.

In Figs. 7 and Sthe body 21 isformed from a special rolled section and the, web is cut to form lugs 22 and'23 and arms 24 and 25 folded overin opposite directions as at 26 and 27. In this case the ends ofthe arms are bent back parallel to each other. The

corners 28 and 29 of the lugs may be bent over if desired to increase the anchor effect.

In Figs. 9 and 10 the body 31has-the arms 32 and 33 folded as at st nd as. The blank is cut on an angle as shown at 36 and the arms thus formed are twisted or folded around so as to make the desired angle leaving the lugs 37, 37 between. Perforations such as 38 may be provided. The edge may be reinforced by a separately formed bead 39.

Theform shown in Fig. 11 is suitable for an interior angle. The edge 41 is doubled.

and formsagroove or channel. The lugs 42 and 4:3 and the arms A4; and d are formed by. cutting the rear edge'of the body as in Fig. 4 then splittingv the lugs of Fig. l between the arms and bending one half with 'its. arm folded over on one side and the V other half with its arm folded over on the other side.

One of the advantages of this invention is that the structure can be made from a relatively narrow strip ofmetal with the body and arms integral, the arms being of considerable length, and without any waste of 'material. v v

. The structure may be painted or galvanized if desired. What Iclaim is:

1. A corner bead formed from a narrow strip of metaland comprising a longitudinal a the lugs and the arms of each set lying flat in their respective planes;

' body portion, a plurality of lugs projecting rearwardly therefrom and "arms integral therewith and arranged in two sets in diverging planes, the lugs being between the planes of the arms and forming stops for the bead and the arms being folded over upon 12. 'A corner bead comprising a longitudinal body portion having lugs integral therewith along the rear edge, and arms integrally connected withsaid lugs and sep- 9 arated from each other, the separate arms being folded over against the lugs to which they are connected and the free ends of the a separate arms projecting laterally at right angles from the body portion beyond said lugs.

' 3.A' corner bead comprising alongitudinally foldedbody portion, a series of spacing lu'gsiarranged pairs opposite each other along the rear edges thereof and arms integral with said lugs having disconnected free I ends folded over against said lugs and pro- ,jecting laterally therefrom. j I 4; A corner bead formed from a relatively narrowfistrip of metal bent longitudinally along-the center thereofand having two sidesr connected along'the front edge, the

said sides having cuts made thereinextend ing from the rear edges of the same inward into the bodyof the sides and substantially longitudinally thereof to thereby provide longitudinalfarm portions along the rear edges of'the sides each connected at one end A with the side from which it is cut and separated from said sidefor therest of its length, thefree ends ofsaid longitudinally detached'edge arm portions of the sides being bent out of the planes of the sides and rearwardly in respect to the frontv edge of' the structure whereby to provide a relatively narrow corner bead structure with relatively long separate attaching arms having free ends extending rearwardly a considerable distance beyond the normal rear edges of the bent strip.

.5. A corner strip of metal and comprising a body portion folded along its center to form a double outer edge to the body, lugs and arms integrally connected with the sides of the body, said arms being cut from the side edges of the body and bent outwardly and'rearwardly, the parts of the arms at the points 1 of attachment with the sides of the body be ing bent over double upon themselves and the ends of the arms extending free from the body substantially at right angles to the length of the body whereby a corner bead constructionwith attaching arms is formed from a relatively narrow strip of metal, said lugs being located between the arms for spacing the front edge away from a corner and leaving plaster-bonding openingsin the sides where the ends of the arms have been bent'outwardly. I

6. A corner bead comprising'a'narrow strip of metal folded along the center to form a 'body'with a rounded front edge, lugs integrally connected to the rear edges of the body and projecting rearwardly therefrom lugs, arms integrally connected with the sideedges of said lugs and projecting out wardly and rearwardly therefrom, said arms being cut from the rear edges of the body between saidlugs and turned over inside out.
